POS cash registers are widely used in physical stores across our industries. Cash register accessories also play different important roles, and customer displays are no exception. The biggest role of customer display is to let the customer pay at the checkout, which can intuitive see the consumption amount, the amount of change. Not only convenient for the cashier understanding of product information and price, also makes the cashier method and results presented transparent in front of customers, more close to the distance between businesses and consumers.

What if the customer display screen does not show?

There are many reasons for this, but let’s make them in the following order:

(1) First, to connect the power supply separately, do not connect the serial port, and see whether the initialization screen (display baud rate information) appears. If there is no initialization screen, judge the power failure.

(2) Check whether the host power supply is normal and whether the power cable is disconnected. If there is an initialization screen, you can plug in the serial port, and download the corresponding test program from the website for testing. If the test is not normal, determine the signal fault.

(3) Check whether the serial port of the host is normal and whether the signal cable is intact. If the test software is normal, the hardware is not faulty. Check whether the software supports the customer’s display screen and the Settings are correct.
